Company Description

At Maxima, we’re building an agentic AI platform to automate enterprise accounting with intelligent, action-oriented systems. Our platform handles high-volume financial data, complex accounting workflows, and robust, reliable executions that must be precise and accurate.

We’re tackling some of the hardest problems in enterprise automation and have assembled a world-class team with staff-level talent from Robinhood, Glean, Google, Netflix, and Meta. Maxima is backed by top-tier investors including Kleiner Perkins and Redpoint Ventures and trusted by customers like Scale AI and Rippling.

Role Overview

As a senior/staff software engineer on our AI Agents team, you will take the lead on building and scaling the core agentic systems that power real-world enterprise accounting automation. This role spans the full lifecycle of AI agent architecture, implementation, deployment, and optimization. You’ll confront and solve hard distributed systems and intelligent automation challenges, working closely with stakeholders at the intersection of software engineering, AI, and enterprise operations.

Key Challenges

• Architect durable, highly-available, and scalable financial data processing layers to support the work of agents.

• Construct low-latency, extensible infrastructure to enable the deployment and iteration of next-gen agents.

• Solve intricate enterprise accounting workflows through robust, composable abstractions and AI-driven automation.

You’ll be expected to own mission-critical product and engineering areas, regularly engage with customers to understand real-world requirements, and help drive the roadmap for our AI automation platform. We value engineers with strong technical foundations who demonstrate initiative, curiosity, and the ability to iterate quickly.

• Demonstrated experience architecting, building, or maintaining AI agent harnesses and agentic platforms.

• Strong familiarity with web development, relational databases, distributed and data-intensive systems.

• Proven ability to design, deploy, and iterate on scalable infrastructure and automation components for AI-driven workflows.

• Deep interest in AI agent architectures, workflow engines, data pipelines, or mission-critical automation in domains like fintech or enterprise software.

• Strong communication and collaboration skills, and an eagerness to contribute cross-functionally.

• Passion for in-person teamwork: we are in office, 5 days a week in downtown San Mateo.

Why Join Us:

• Be a core part of a mission-driven team redefining how the world’s leading companies do accounting.

• Directly impact our product, technical direction, and the broader AI agent landscape.
